DZUL-CAUICH Instituto de Ecología A.C., Red de Interacciones Multitróficas. Carretera antigua a Coatepec # 351, El Haya. Xalapa, Veracruz 91070, México. E-mail: francisco.dzul@inecol.mx 1 Corresponding author: E-mail: vicente.hernandez@inecol.mx Abstract Neotraginops mexicanus n. sp. is described and illustrated based on specimens from Mexico and Belize, representing the second known species for the genus. Additional records for Odinia coronata Sabrosky from Mexico and Nicaragua are provided. Keywords: Schizophora, Opomyzoidea, Neotropical Region Introduction The family Odiniidae comprises near 60 described extant species classified into 14 genera of two subfamilies (Odiniinae and Traginopinae), which are distributed in almost all biogeographical regions (Gaimari & Mathis 2011). In the Neotropical Region the presence of 26 species have been recorded, including three genera and five species recently described from Brazil and Costa Rica (Gaimari 2007; Carvalho-Filho et al. 2009). This family is represented in Mexico by only two species, Odinia coronata Sabrosky, with records from the states of Morelos and Chiapas, and Schildomyia reticulata Prado from the state of Veracruz (Gaimari & Mathis 2011). The genus Traginops Coquillett was described for the Nearctic species T. irroratus (Coquillett 1900). The genus was later rediagnosed by Hendel (1909) to incorporate a second species, T. clathratus Hendel, from Peru and Paraguay. Based on morphological features of the male genitalia observed in T. orientalis Meijere (Hennig 1938), and the Nearctic T. irroratus and T. purpurops Steyskal (Steyskal 1963), the new genus Neotraginops was described by Prado (1973) to separate out the single Neotropical species N. clathratus. Having been described from Peru (Vilcanota) and Paraguay, additional distributional data were recorded for Brazil (Mato Grosso, Goiás, Minas Gerais, Espírito Santo, Rio de Janeiro, Guanabara, São Paulo, Santa Catarina), and Colombia (Prado 1973; 1975). Gaimari (2010) referred to the presence of three undescribed species from Costa Rica, Belize and Panama; the one from Belize is part of the paratype series for the new species described herein. In this work a second species of the genus Neotraginops is described, on the basis of specimens collected in the states of Guerrero and Veracruz (Mexico), and a male from Belize. Also new data of the distribution of Odinia coronata for Mexico and Nicaragua are provided. Material and methods The material examined from various collections in the states of Veracruz and Guerrero (Mexico) were mainly obtained through the use of McPhail traps baited with hydrolyzed protein as attractant, but also recovered from Malaise traps and rotten-fruit traps. Specimens were preserved in 75% alcohol, and later dry mounted on insect pins. The analysis of the genitalia of both sexes was performed by removing and placing the abdomens in a 10% NaOH solution and heating for several minutes; thereafter, the structures were rinsed in distilled water and Accepted by S.

preserved in microvials with glycerin, mounted on the pin below the corresponding specimen. The wings were mounted on permanent slides in Canada Balsam. Digital micrographs were made using an Olympus C5050 camera adapted to Olympus BX41 and SZX7 microscopes. The taxonomic nomenclature used in the study follows the work of Gaimari (2007, 2010). Studied specimens were deposited in the entomological collections of the Instituto de Ecologia AC IEXA (Xalapa, Mexico), the National Collection of Insects of the Instituto de Biologia UNAM CNIN (Mexico DF), and one paratype of the new species belongs to the National Museum of Natural History, Smithsonian Institution USNM (Washington DC, USA). Neotraginops Prado, 1973 Diagnosis. Head with a large rounded tubercle on the ocellar area (similar to Traginops and Paratraginops Hendel), covered by dark setulae extending to the inner vertical setae; antenna short with third antennal segment rounded apically, arista pubescent; gena broad; oral vibrissa and subvibrissal setae present; ocellar setae long; 3 pairs of fronto-orbital setae present, the anteriormost seta inclinate and posterior setae reclinate; 1 inner and 1 outer vertical setae. Chaetotaxy of the thorax as follows: 1 postpronotal, usually flanked by two short setae; 2 notopleurals, 1 supra-alar presutural, 2 supra-alar postsuturals (anterior pair weak), 2 postalars, 1 intrapostalar, 4 dorsocentrals (anterior pair presutural and remaining three postsutural), 1 acrostichal, 2 propleurals, 3 katepisternals, 2 scutellars with scutellum setulose on disc. Wing with subcostal vein nearly complete, evanescent distally separated from R 1 ; crossvein r-m located at apical third of discal cell; veins R 4+5 and M 1 almost straight, subparallel; anal vein long, almost reaching the posterior margin of wing; crossvein dm-cu straight; legs with femora strong; one short preapical dorsal seta present on all tibiae, and an apical ventral seta on mid tibia twice as long as the preapical dorsal seta. Remarks. The ocellar tubercle being well developed is a feature shared with Paratraginops and Traginops. The genus Neotraginops differs from the related genus Paratraginops in that the latter having a plumose arista, and vein M 1 being strongly curved anteriorly towards the apex. In contrast, the pubescent arista and the straight vein M 1 are characters shared with Traginops, from which Neotraginops can be differentiated by the presence of two propleural setae, besides its distribution being restricted to the Neotropical Region.
